Description

Technical Field

[0001] This utility model relates to the field of strength testing technology, specifically a strength testing device for cement mixing piles. Background Technology

[0002] In recent years, cement-soil mixing piles have been frequently used for reinforcement when dealing with soft foundations such as silt, silty soil, silty clay, and silty mud. Cement-soil mixing piles are "cement-soil piles" made by thoroughly mixing cement and a small amount of additives with the foundation soil on-site. They have advantages such as low cost, convenient construction, and no environmental pollution. However, they require high-level construction techniques. During construction, the ratio of cement to soil and the uniformity of mixing are difficult to control. Poor control can easily lead to quality problems. Common issues include uneven mixing of cement and soil, resulting in areas with insufficient or no cement. To determine the quality of the cement mixture, a portion of the pile is taken for strength testing.

[0003] Utility model patent CN218027878U discloses a novel cement mixing pile strength testing device, belonging to the technical field of strength testing. It addresses the problem in existing technologies where, during the testing of the compressive strength of cement mixing piles, the cement column breaks under pressure, causing concrete fragments to splatter. This not only poses a risk of injury to testers or objects outside the testing device but also makes subsequent cleanup difficult. The device includes a main body with a base box on one side. Support columns are fixedly connected to the top of the base box around its four sides. Three side plates are fixedly installed between the four support columns. A door is hinged to the outer wall of one of the support columns. A top plate is bolted to the top of the four support columns. A tray is installed on the inner side between the four support columns. During testing, when the cement pile exceeds its strength limit and breaks, the splattered fragments are blocked by the side plates and the door, allowing them to fall into the tray, thus preventing injury from flying debris and ensuring the safety of the testing personnel.

[0004] However, the above patent still has shortcomings: although it can perform strength testing on cement mixing piles, it does not have the function of centering the cement mixing piles, which causes the cement mixing piles to deviate from the pressure point, resulting in inaccurate test data.

[0005] To overcome the above deficiencies, this utility model provides a cement mixing pile strength testing device to solve the problem mentioned in the background art that although the existing cement mixing pile strength testing device can test the strength of cement mixing piles, it does not have the function of centering the cement mixing pile, which causes the cement mixing pile to deviate from the pressure point, resulting in inaccurate test data.

[0006] The technical solution of this utility model is:

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A cement mixing pile strength testing device includes: a testing box 1; a partition 2 is fixedly connected inside the testing box 1, a cement pile body 3 is set at the top center of the partition 2, positioning claws 4 are set at the four corners of the bottom of the cement pile body 3, and moving blocks 5 are fixedly connected to the bottom of each positioning claw 4, and the moving blocks 5 are slidably connected to the partition 2; a clamping mechanism 6 for positioning the cement pile body 3 is set at the bottom of the moving blocks 5; a pressure mechanism 7 for testing the strength of the cement pile body 3 is set at the top of the testing box 1. The user places the cement pile body 3 at the top center of the partition 2, and then controls the moving blocks 5 at the four corners of the partition 2 to move simultaneously toward the cement pile body 3 through the clamping mechanism 6. As the moving blocks 5 move, they respectively drive the positioning claws 4, so that the four positioning claws 4 cooperate to position and clamp the cement pile body 3. Then, the pressure mechanism 7 applies pressure to the cement pile body 3, thereby testing the strength of the cement pile body 3.

[0027] like Figures 3 to 5As shown, the clamping mechanism 6 includes: a first rotating shaft 8 fixedly connected to the bottom center of each movable block 5; a linkage rod 9 rotatably connected to the outer surface of each first rotating shaft 8; a second rotating shaft 10 rotatably connected to the end of each linkage rod 9 away from the first rotating shaft 8; the second rotating shaft 10 being fixed to the four corners of the rotating plate 11; a third rotating shaft 12 fixedly connected to the center of the rotating plate 11; the top of the third rotating shaft 12 rotatably connected to the partition plate 2; and the bottom of the third rotating shaft 12 rotatably connected to the detection box 1; a worm gear 13 fixedly connected to the middle of the third rotating shaft 12; a worm 14 meshing with one side of the worm gear 13; a fourth rotating shaft 15 fixedly connected to the center of the worm 14; one end of the fourth rotating shaft 15 rotatably connected to the detection box 1; and the other end of the fourth rotating shaft 15... The fourth rotating shaft 15 is fixedly connected to the output end of the motor 16, passing through the detection box 1 and extending to the motor 16. When the motor 16 is started, the output end of the motor 16 drives the fourth rotating shaft 15 to rotate. While the fourth rotating shaft 15 rotates, it drives the worm gear 14. The worm gear 14 drives the worm wheel 13. The worm wheel 13 drives the third rotating shaft 12 to rotate. The third rotating shaft 12 rotates by the cooperation of the detection box 1 and the partition plate 2. While the third rotating shaft 12 rotates, it drives the rotating plate 11. While the rotating plate 11 rotates, it drives the second rotating shaft 10 to rotate. While the second rotating shaft 10 rotates, it pulls one end of the linkage rod 9, so that the other end of the linkage rod 9 pulls the first rotating shaft 8. The first rotating shaft 8 drives the moving block 5 to move towards the cement pile body 3.

[0028] like Figure 4 and Figure 5 As shown, sliding grooves 17 are provided on both sides of the movable block 5. Limiting slide bars 18 are fixedly connected to the partition plate 2 near the sliding grooves 17. The movable block 5 is slidably connected to the limiting slide bars 18 through the sliding grooves 17, which can limit the movement stroke of the movable block 5, so that the movable block 5 can slide flexibly horizontally inside the partition plate 2.

[0029] like Figure 2 As shown, the pressure mechanism 7 includes: a hydraulic cylinder 19 fixedly connected to the top center of the detection box 1, the telescopic end of the hydraulic cylinder 19 passing through the detection box 1 and extending to the pressure sensor 20, the pressure sensor 20 being fixedly connected to the telescopic end of the hydraulic cylinder 19; a pressure plate 21 fixedly connected to the bottom of the pressure sensor 20, the pressure plate 21 cooperating with the cement pile body 3, when the hydraulic cylinder 19 is activated, the telescopic end of the hydraulic cylinder 19 drives the pressure sensor 20, the pressure sensor 20 drives the pressure plate 21, so that the pressure plate 21 applies pressure to the cement pile body 3, while applying pressure to the cement pile body 3, the pressure sensor 20 can detect the pressure value, and thus detect the strength of the cement pile body 3.

[0030] like Figure 1As shown, a door 22 is provided on one side of the testing box 1. The door 22 is hinged to the testing box 1 by two hinges 23. A tempered glass 24 is fixedly connected to the center of the door 22. A handle 25 is provided on one side of the tempered glass 24 and is fixedly connected to the door 22. A control box 26 with an internal touch screen is provided on the top of the door 22. The control box 26 is fixedly connected to the testing box 1. It can prevent the cement pile body 3 from splashing when it breaks, thereby achieving the purpose of protecting workers. The control box 26 also makes it convenient for users to operate the device and view the strength test data of the cement pile body 3.

[0031] like Figure 1 and Figure 2 As shown, each of the four corners of the bottom of the test box 1 is equipped with a universal wheel 27 with a braking function. The universal wheel 27 is fixedly connected to the test box 1, which makes it convenient for users to move and fix the device.

[0032] like Figure 4 As shown, damping pads 28 are provided between the positioning claw 4 and the cement pile body 3. The damping pads 28 are fixedly connected to the positioning claw 4, which improves the friction between the positioning claw 4 and the cement pile body 3, thereby improving the stability of clamping the cement pile body 3.

[0033] Working principle: The user places the cement pile body 3 at the top center of the partition 2, and then starts the motor 16. The output end of the motor 16 drives the fourth rotating shaft 15 to rotate. The rotation of the fourth rotating shaft 15 drives the worm gear 14, the worm gear 14 drives the worm wheel 13, and the worm wheel 13 drives the third rotating shaft 12 to rotate. The third rotating shaft 12 rotates by the cooperation of the detection box 1 and the partition 2. The rotation of the third rotating shaft 12 drives the rotating plate 11. The rotation of the rotating plate 11 drives the second rotating shaft 10 to rotate. As the second rotating shaft 10 rotates, it pulls one end of the linkage rod 9, causing the other end of the linkage rod 9 to pull the first rotating shaft 8. A rotating shaft 8 drives a moving block 5 to move towards the cement pile body 3. As the moving block 5 moves, it drives the positioning claws 4 respectively, so that the four positioning claws 4 cooperate to position and clamp the cement pile body 3. This can center and clamp the cement mixing pile, so that the cement mixing pile is located at the center of the device. This improves the accuracy of the strength test data of the cement mixing pile and solves the problem that although the existing cement mixing pile strength test device can test the strength of the cement mixing pile, it does not have the function of center positioning of the cement mixing pile, which causes the cement mixing pile to deviate from the pressure point and the test data to be inaccurate.

[0034] Start the hydraulic cylinder 19. The extension and retraction end of the hydraulic cylinder 19 drives the pressure sensor 20. The pressure sensor 20 drives the pressure plate 21, so that the pressure plate 21 applies pressure to the cement pile body 3. While applying pressure to the cement pile body 3, the pressure sensor 20 can detect the pressure value, and thus detect the strength of the cement pile body 3.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
